Preheat oven to 400 degrees F. Line muffin tins with paper liners or coat with vegetable spray.
In large bowl, combine together the flour, baking soda, baking powder, cinnamon, brown sugar, and granulated sugar, mixing well. In another bowl, combine the milk, mashed yams, orange rind, orange juice, egg, egg white, oil, and vanilla.
Add the liquid ingredients to the dry ingredients, mixing just until moistened. Spoon the batter into prepared muffin tins, filling 2/3 full. Bake 20 to 25 minutes, or until muffins are done.
